The cutting blade 2 that is produced by processing is a processing fragment (machined chip) or a converted products (machined product).In either case, cutting blade 2 is fallen in the cutting blade reception basket 30.According to characteristics of the present invention, cutting blade receives basket 30 by rotating support, so that it can rotate around a trunnion axis, and this cutting blade receives the basket execution and rotatablely moves to realize a upturned position, thereby make and from cutting blade reception basket 30, shift out from the cutting blade 2 that receives, from the recovery on every side of bootstrap block 8 down, and be transferred to then in the cutting blade collecting box 40.This mechanism with and the operation will be described below.
As shown in Figure 5, cutting blade receives basket 30 and is installed on the support bar (support component) 31, and by its support, this support bar 31 and a rotation back shaft 36 are coupled.Rotation back shaft 36 is supported by following bootstrap block 8 by the bearing (not shown).Generally (that is to say, do not carry out in the operating time of recovery cutting material cited below), support bar 31 and be rotated back shaft 36 and support cutting blade with rotation and receive basket 30 and keep static, and under free state, be placed on down on the bootstrap block 8.The cutting blade 2 that falls down is cut sheet and receives basket 30 receptions.
One in the support bar 31 has an extension 32, and it extends away from rotation back shaft 36.This extension 32 is as making support bar 31 and receiving the levers (action bars) of basket 30 around 36 rotations of rotation back shaft by the cutting blade of this they sup-port.By a moment motion around rotation back shaft 36 is acted on extension 32, this cutting blade receives basket 30 and rotates around this rotation back shaft 36.
What moment application apparatus in the present embodiment adopted is a mechanism, and this mechanism is converted to moment loading around rotation back shaft 36 with the driving force of XY platform 4, and this mechanism with this moment be applied to extension 32 tips around.Especially, a bearing 33 be positioned at extension 32 tips around so that its a little to the side outstanding (rotation back shaft 36 axially); And a cam bit 34 is provided, it forms one bearing 33 is contained in wherein groove (guide channel) 35 suitably.
Cutting blade collecting box 40 has an opening of upwards (bearing the Z direction), and this cutting collecting box 40 receives basket 30 with cutting blade and arranges with respect to rotation back shaft 36 near symmetrical.In the present embodiment, cutting blade collecting box 40 is arranged in processing case 20.In some cases, cutting blade collecting box 40 can be positioned at outside the processing case 20.Cam bit 34 is fixed on the position (having omitted the figure of standing part) near cutting blade collecting box 40 in the processing case 20, thereby, cutting material on following bootstrap block 8 receives the position relation between basket 30 and the cam bit 34 still, and basket 30 and the position between the groove on the cam bit 34 35 concern and determine according to the movement position of XY platform 4.
In the present embodiment, cam bit 34 is arranged in such a way: when in the process of processing work 1, when XY platform 4 moved in the scope of its expection, the bearing 33 of extension 32 and support bar 31 kept clear of cam bit 34.Therefore,, there is not moment to be applied on extension 32 and the bearing 33 when the normal discharge of workpiece 1 execution adds man-hour, thereby, as described above, under being positioned at still, cutting blade reception basket 30 on the bootstrap block 8, prepares to receive the cutting blade 2 that falls.
Next describe the operation of reclaiming and collecting cutting blade (being sent in the cutting blade collecting box 40), it is realized by utilizing rotating mechanism above-mentioned.
By cutting blade being received basket 30 around 36 rotations of rotation back shaft, cutting blade 2 and cutting blade receive basket 30 and remove around bootstrap block 8 down together, thereby realize the recovery of cutting blade 2.Cutting blade receives basket 30 and is further rotated, upset then, thus Open Side Down points to cutting blade collecting box 40 for it, thus cutting blade 2 can be transferred in the cutting blade collecting box 40.
In order to make cutting blade receive basket 30 around 36 rotations of rotation back shaft, as shown in Figure 5, utilize the driving shaft of XY platform, bearing 33 moves to towards the position of cam bit 34 gap slots 35.For convenience of description, this XY position (measuring (with following identical) with Y-axis along X-axis) is called " recovery ready position ".Reclaim ready position from this, bearing 33 moves up a preset distance to be fixed in the groove 35 at the X losing side.The XY position that this bearing fixing is finished also is the position that X-axis and Y-axis were replied after recovery/collection was finished.For convenience of description, such position is called " reclaiming beginning/completing place ".
Fig. 7 has shown that this XY position is for reclaiming the state of beginning/completing place.Especially, because from reclaiming the motion (along the moving of negative directions X) of ready position to recovery/completing place, bearing 33 along the inside direction of relative drawing, moves the position of a predetermined distance (from reclaiming ready position to the distance that reclaims between the beginning/completing place) to the groove 35 that is installed in cam bit 34 in Fig. 7.At this state, cutting blade receives basket 30 and still just is positioned at still on this lower guideway 8 by support bar 31 certainly.
Next, when Y-axis (is negative Y direction (to Fig. 7 left side) here) when state shown in Figure 7 further is rotated, bearing 33 is constrained in the groove 35, and by groove 35 guided-movings.As a result, moment imposes on the extension 32 of support bar 31 with the direction around rotation back shaft 36, and this support bar 31 receives basket 30 with cutting blade and begins around 36 rotations of rotation back shaft.Fig. 8 a and 8b have shown that respectively cutting blade receives the state of about 60 degree of basket 30 rotations and 90 degree.
Then, Y-axis continues to move, and rotates to the upturned position that is positioned on the cutting blade collecting box 40 thereby cutting blade receives basket 30.This rollover states as shown in Figure 9.In this example, when 30 rotations about 120 of cutting blade reception basket are spent, reach the rotation boundary.This state keeps a preset time cycle, thereby cutting blade 2 is transferred in the cutting blade collecting box 40 from cutting blade reception basket 30.
For convenience of explanation, the XY position corresponding to state shown in Figure 9 is referred to as " cutting blade receives the basket upturned position ".
After having passed through predetermined period of time, Y-axis is being moved in the opposite direction with reclaimer operation side, thus the state by Fig. 8 b and Fig. 8 a, the state (recovery/completing place) of Y-axis from the replying state of Fig. 9 to Fig. 7.When the answer that realizes from Fig. 7 to Fig. 5 state, the engagement between release bearing 33 and the groove 35, thus the XY platform can move freely, and cutting blade receives basket 30 and remains on its its original orientation (not rotation status) still.Above-described a series of whole demonstration the among Figure 10 that operate in.It below is the emphasis of each step.
Step S1:X axle and Y-axis move to the previously described recovery ready position in the controller.
Step S2:X axle moves a predetermined distance d 1 at negative directions X.This predetermined distance d 1 for make bearing 33 be installed to from position suitable shown in Figure 5 ground the groove 35 must and enough distances.This sets in advance in controller apart from d1.
Step S3:Y axle moves a predetermined distance d 2 in negative Y direction, this predetermined distance d 2 for make cutting blade receive the state (cutting blade receive a basket upturned position) of basket 30 when state shown in Figure 7 (recoverys/completing place) rotates to Fig. 9 institute must and enough Y-axis move distances.This sets in advance in controller apart from d2.
Step S4: cutting blade receives basket 30 and keeps stopping a predetermined period of time T, and this time cycle is for guaranteeing that cutting blade 2 receives basket 30 from cutting blade and falls into cutting blade the collecting box essential and time enough cycle (for example, several seconds) of 40 institutes.This period of time T sets in advance in controller.
Step S5:Y axle moves a predetermined distance d 2 so that return back to state shown in Figure 7 (reclaiming beginning/completing place) in positive Y direction.
Step S6:X axle moves a predetermined distance d 1 so that return back to state shown in Figure 5 (recovery ready position) at positive directions X.
The advantage of embodiment above-mentioned is: realize that the rotary driving force of cutting blade recovery/collection can obtain from the work stage driving shaft because make cutting blade receive basket, and this work stage driving shaft just must be assemblied in the wire electric discharge apparatus originally, so neither need cylinder also not need the motor of a specific use; Present embodiment is not subject to semi-solid influence of producing (sludge produced) in process, thereby has higher reliability in operation.Another advantage is that whole cost of manufacture is very low.
